Cops said a neighbor called 911 around 8:30 p.m. Sunday to report an injured woman outside a residence on Headen Way in Rivermark, a high-end neighborhood in Santa Clara, Calif.

Cops arrived and found a grisly scene with five slaughtered inside, all shot. The suspected gunman was dead on the top floor with a self-inflicted gunshot wound, police said.

Investigators said the suspect lived at the recently rented house with his wife and their two kids, the deceased 11-year-old boy and 4 year-old girl.

The other victims - a young married couple and their toddler daughter - had recently arrived from India and are believed to be relatives of the alleged killer's wife.

Investigators said financial issues did not appear to be a factor in the massacre.

"It's devastating for everybody involved, the victims, the community and the first responders," said Cpt. Mike Sellers. "Some of our officers performed CPR on the girl who was around 4 years old, but she was pronounced dead at the scene."

Sellers said he did not believe the suspect, believed to be in his mid 40s and of Indian descent, left a suicide note. The triggerman reportedly was an engineer at Yahoo who also had worked at Microsoft, according to the San Jose Mercury News.
